'You know me then?' asked the Doctor, a little tentatively.
'You're the Doctor,' replied Fitz, a slight frown worming its way onto his forehead.
'Yes, yes, yes, the Doctor, of course I am,' The Doctor smiled, genuinely pleased to see a familiar face, even if for the moment he couldn't quite put a name to it. 'But, er, Doctor who?' he added hopefully.

Can the Doctor find Dave before the alien contact proves fatal? Who are the secret agents keeping tabs on the rival Space Race teams? Will the Doctor's mysterious blue box finally reveal its purpose? And does the Doctor, now truly a man without a past, have what it takes to stop the Kulan Invasion of Earth...?
